The Serial Port dialog (page 8–5) contains a check box for Enable
Pass-Through to DeviceNet. With this box selected, data from the
serial port is passed through to a DeviceNet master-slave network.

To connect a device such as a decoded hand-held scanner, you will
need to create a custom cable. The AdpataScan Reader user manual
(Publication 2755-837) shows the AdaptaScan serial port
connections.
In the above example, the scanner data is input directly into the
AdaptaScan RS-232 serial port. The AdaptaScan reader outputs the
data to its DeviceNet port. To the rest of the DeviceNet network it
appears that the data is coming directly from the reader.
Note: If the serial port receives more characters than the controller
is configured to accept, 0s will appear in the data field. The 0s
indicate that the file size is being exceeded.
